Was Mu'awiyah a Nasibi?

[Africanshia1]

As Salamu Alaikum,

I was following a discussion between a Sunni and a Shi'i, one of the points the Shi'i brought up from ibn kathir was concerning Mu'awiyah being a Nasibi. How true is this:

# Ibn Kathir summarised the Khulafah of Banu Umayyad as Nasibiyyun:

The Khalifas from Banu Umayyah were like this … ALL OF THEM were Nasibis, except Imam ‘Umar the Pious: Mu'awiyah,
then his son Yazid , then his grandson Mu’awiyah al-Sadid; Marwan, then his son ‘Abd Al-Malik ….

[Hani]

He had a war with Ali, of course he's classed as Nasibi. I wouldn't generalize and say they were all like this without proof.

Before this, you need to define the word Nasibi, please ask this Shia to define Nasb.
